The GLS85VM1016T / 1032T / 1064T eMMC
NANDrive™ VX Series devices (referred to as “eMMC
NANDrive” in this datasheet) are fully integrated solidstate drives. They combine an advanced NAND
controller and 16, 32 or 64 GBytes of NAND flash
memory in a multi-chip package. These products are
ideal for embedded and portable applications that
require small form-factor, energy efficient and reliabledata storage.

The integrated NAND flash controller with built-in
advanced NAND management firmware communicateswith the host through the standard eMMC protocol. It
does not require any additional or proprietary software
such as the Flash File System (FFS) and Memory
Technology Driver (MTD).
eMMC NANDrive’s advanced NAND management
technology enhances data security, improves
endurance and accurately tracks the usage of theNAND flash. This innovative technology combinesrobust error correction capabilities with advanced
wear-leveling algorithms and bad block management
to extend the life of the product.

eMMC solid state drives are widely used in GPS andtelematics, in-vehicle infotainment, portable andindustrial computers, handheld data collection
scanners, point-of-sale terminals, networking andtelecommunications equipment, robotics, audio andvideo recorders, monitoring devices and set-top boxes.

eMMC NANDrive supports Single Data Rate (SDR)
and Dual Data Rate (DDR) modes, HS200 mode,
HS400 mode, boot, multiple partitions, permanent andpartial write protect, Replay Protected Memory Block(RPMB) access, Sanitize and TRIM, hardware resetand other features detailed in the eMMC 5.1 standard
specification. It is backward compatible with previous
eMMC standards.

eMMC NANDrive provides complete eMMC solid statedrive (SSD) functionality and compatibility in an
11.5mm x 13mm BGA package for easy, spacesaving mounting to a system motherboard. With its
small size, low power consumption, strong security,
reliability and ruggedness, eMMC NANDrive
surpasses removable storage and discrete NANDbased products.

GENERAL DESCRIPTION

Each eMMC NANDrive contains an integrated eMMC NAND flash memory controller and NAND flash die in a
BGA package. Refer to Figure 2-1 for the eMMC NANDrive block diagram.

1.1

1.1.5 Error Checking and Correction (ECC)
The ECC technology uses advanced Low Density
Parity Check (LDPC) algorithms to detect and correct
errors, ensuring data integrity and extending the SSD
lifespan.

Optimized eMMC NANDrive

The heart of the eMMC NANDrive is the eMMC NAND
flash memory controller, which translates standard
eMMC signals into flash media data and control
signals. The following components contribute to theeMMC NANDrive’s operation.

1.1.6 Multi-tasking Interface
The multi-tasking interface enables fast, sequential
write performance by allowing concurrent Read,
Program and Erase operations to multiple flash media.

1.1.1 Microcontroller Unit (MCU)
The MCU transfers the eMMC commands into dataand control signals required for flash media operation.

1.2

1.1.2 Internal Direct Memory Access (DMA)
The eMMC NANDrive uses internal DMA allowing
instant data transfer from/to buffer to/from flash media.
This implementation eliminates microcontroller
overhead associated with the traditional, firmwarebased approach, thereby increasing the data transferrate.

SMT Reflow Consideration

The eMMC NANDrive family utilizes standard NAND
flash for data storage. Because the high temperature
in a surface-mount reflow soldering process may alter
the content on NAND flash, it is recommended toprogram the eMMC NANDrive after the reflow process.

1.3

1.1.3 Power Management Unit (PMU)
The PMU controls the power consumption of theeMMC NANDrive. The PMU dramatically reduces thepower consumption of the eMMC NANDrive by putting
the part of the circuitry that is not in operation into
Sleep mode.

Advanced NAND Management

eMMC NANDrive’s integrated controller uses
advanced wear-leveling algorithms to substantially
increase the longevity of NAND flash media. Wearcaused by data writes is evenly distributed in all or
select blocks in the device that prevents “hot spots” inlocations that are programmed and erased extensively.
This effective wear-leveling technique results in
optimized device endurance, enhanced data retention
and higher reliability required by long-life applications.

The Flash File System handles inadvertent powerinterrupts and has auto-recovery capability to ensure
the eMMC NANDrive’s data integrity.
1.1.4 Embedded Flash File System
The embedded flash file system is an integral part ofthe eMMC NANDrive. It is integrated in the controller’s
firmware that performs the following tasks:
1. Manages and optimizes the data access of flash
media
2. Provides flash media wear leveling to spread
flash writes across all memory address space toincrease the longevity of flash media
3. Keeps track of the data file structureThese specifications are subject to change without notice.
